The altitude of a triangle is a perpendicular segment from the vertex to a line containing the

Mathematics

azamat3 years ago

Answer:

H=\sqrt{91}

Step-by-step explanation:

The altitude falls in the middle of the line.

So, the point at which it falls in the bottom line is the midpoint, so the length of the blue triangle would be 6/2 = 3

So, the blue triangle has length of 3 and height of H and hypotenuse of 10.

Now, we will use Pythagorean Theorem to solve for H. The theorem is:

Leg^2 + Another Leg^2 = Hypotenuse^2

We know one leg of the triangle is 3 and another leg is H and hypotenuse is 10, so we substitute and solve:

3^2 + H^2 = 10^2\\9+H^2=100\\H^2=100-9\\H^2=91\\H=\sqrt{91}

This is the exact answer for H

Step-by-step explanation:

Rotational symmetry is when a shape has the same orientation after being rotated.

For example, an equilateral triangle rotated 120° will line back up with itself.  A square rotated 90° will also return to its original orientation.  Same with a pentagon rotated 72°.

Basically, an n-gon rotated by a multiple of 360°/n will return to its original position.

θ = k 360°/n

For the first rotation:

160° = k 360°/n

160 / 360 = k / n

4/9 = k/n

For the second rotation:

120° = k 360°/n

120 / 360 = k / n

1/3 = k/n

For the third rotation:

80° = k 360°/n

80 / 360 = k / n

2/9 = k/n

For the fourth rotation:

280° = k 360°/n

280 / 360 = k / n

7/9 = k/n

The total rotation angle is -160°.

160 = k 360/n

160 / 360 = k / n

4/9 = k/n

Comparing the denominators, n must be the smallest multiple of 3 and 9.  Therefore, n = 9.

A sail in the form of a right triangle the angle at its lower edge is 55 what is the size of the angle formed at the top of the
Mars2501 [29]

Answer:

The size of the angle formed at the top of the sail is 35.

Step-by-step explanation:

We know that the sum of all angles inside a triangle must be 180. This is a rule.

So we know that a right triangle is called like that because one angle is a 90-degree angle.

Then we have that:

180 = right angle + lower edge angle + angle top of the sail

180 = 90 + 55 + angle top of the sail

Solving for 'angle top of the sail' we have:

angle top of the sail = 180 - 90 - 55 = 35

The size of the angle formed at the top of the sail is 35.

If Lupe walk 0 miles, he will earn $50 for his library fundraiser just by signing up to help. But if Lupe walks 1 mile, he will
wlad13 [49]

Answer:

$10

Step-by-step explanation:

Given that:

Amount earned for 0 mile = $50 (earned for signing up)

Amount earned for walking 1 mile = $60 ($50 for signing up and $10 for. Walking)

Hence, the amount earned per mile walked according to the information given is $10

Total amount earned =. Sign up fee +. Walking fee

$60 = $50 + walking fee

Walking fee = $60 - $50

Walking fee =. $10

Miles walked = 1 mile

Hence , amount earned per mile = $10

The area of a square is 4 square meters. How long is each side? Please show every step.
inessss [21]
Since you're trying to find the side lenghts of a square, all we need to do is square root the area. So, the square root of 4 (the area) is 2.

So, all of the sides of the square are 2 meters long.
